Autonomous System Numbers (ASNs) are assigned to entities such as Internet Service Providers
and other large organizations that control blocks of IP addresses. This network page, and
the organization field that's shown on the main IP address information page and also
returned in the geolocation API are based on the ASN.
The ASN details will often correspond to the IP address owner, but for smaller organizations
it may be that organization's parent, or their ISP.
